Injection machinery maker Arburg GmbH + Co. KG used its annual Technology Days open house at its Lossburg headquarters to launch its energy-saving Hidrive hybrid machine line and show off its newly completed customer center.
The Hidrive H-series machines feature a five-point toggle clamping unit incorporating the electric clamp system from the all-electric Allrounder Alldrive, the hydraulic injection unit from the Allrounder S Advance and the hydraulic accumulator technology from the Allrounder S.
The open house drew about 3,300 visitors in March.
Sales director Helmut Heinson said the new machine has been developed around a limited number of combinations of clamping and injection units for high efficiency in production and cost. As a result, the Hidrive costs 25 percent less than an equivalent Alldrive all-electric machine, the firm said.
The company claims the Hidrive can lead to energy savings of up to 40 percent over a standard hydraulic machine, in part because the Hidrive uses energy recovered during braking and has efficiency-standard EFF1 motors.
Also, hydraulic accumulator charging is dynamically regulated, so the pressure level automatically adjusts in line with demand.
A comparison of dry cycle times shows that a Hidrive 370H can cycle in the same time as its all-electric equivalent 0.8 second while a hydraulic machine with dual-pump technology takes 1.3 seconds, according to Arburg.
Officials said Hidrive reproducibility is similar to that of all-electric machines, due in part to the use of a position-regulated screw on the injection unit and planetary roller screw-drive positioning of the clamp.
Hidrive machines will be available with clamping forces of 60-320 metric tons.
The new machines were showcased in Arburg's new, 108,000-square-foot customer service center. The center houses clean room facilities, a powder injection molding laboratory and network integration capabilities. It is equipped with more than 30 injection presses with clamping forces of 121/2 to 500 tonnes.
